Draining the Old Oil
The first step in changing the oil is to drain the old oil from the engine. Here’s how to do it:
1. Locate the oil drain plug: It’s usually located at the bottom of the engine, near the front of the motor. You may need to refer to your owner’s manual or consult with a mechanic if you’re not sure where it is.

3. Drain the oil into a pan: Use a drain pan to catch the old oil as it drains out. Make sure the pan is positioned under the oil drain plug before you remove it.
4. Allow the oil to drain completely: Let the oil drain completely before proceeding to the next step. This may take several minutes, depending on the amount of oil in your engine.
